METHOD FOR REDUCING DEGRADATION OF ORTHOGONALLY POLARIZED WAVE OF MULTI-FEED DUAL OFFSET REFLECTOR ANTENNA

摘要

PROBLEM TO BE SOLVED: To provide a reflector system of an antenna provided with excellent orthogonally polarized wave performance fed by a feed array. ;SOLUTION: The feed array is provided with a first feed 50 positioned at the almost focus of the reflector and a second feed 45 and a third feed 55 adjacent to the first feed 50 and the second feed 45 and the third feed 55 are rotated by a first size relating to the first feed 50. The array is rotated at a large angle proportionally to a distance from the first feed 50 positioned at the focus in a Y direction and the direction is made opposite on both sides of the first feed 50.;COPYRIGHT: (C)2000,JPO
